Abstract
Electrode-contact pressure controlling involves moving a working electrode (2) against a counter electrode (4) for a downstroke by an electric motor servo-drive under intermediate layer of a welded workpiece. The working electrode is impinged with a reference conact pressure predetermined for a welding process by a determined servo-drive moment at workpiece contact. The electrode-downstroke is examined. A current electrode gap corresponds with a reference-workpiece thickness (W) is predetermined in controller. The drive moment determined for the required contact pressure is predetermined. Independent claims are included for: (1) a method for calibrating an electrode drive, which involves driving the electrode arms with their welding electrodes into a closing position; and (2) an electrode holder, which comprises a collector and a backplate electrode.
